How can planes navigate in fog? How can a GPS (global positioning system) receiver determine its position (and why is it sometimes considerably off the mark)? Radio waves penetrate fog and clouds and have mostly obsoleted the lighthouses of old. In this workshop, we use ultrasonic waves as a model for radio waves. Students use ultrasonic receivers and an oscilloscope to determine their position in the lab using direction (angulation) and time (lateration) measurements.

Syllabus Links:

Physics O-Level: Waves, Interpretation of oscilloscope waveforms. Physics A-Level: Wave motion, Use of an oscilloscope, Mathematics O-Level: Geometry and measurement.
